Honestly, even telling some people you're queer would greatly impact the relationship dynamic. If you feel like you want to let the people in your life know, go for it, you can't control or predict how people will react so that shouldn't be a factor if it's stopping you from living in your truth.

For myself, I've been working on gaining understanding before passing judgements so unless it's a distant acquaintance, there's nothing my friends can tell me that would make me want to abandon them. Now, that doesn't mean I won't grill them to death if it was super egregious.
